in or out, and if out will show the time at which he will be back and to construct such 145v parts for manipulation from the interior ot the door. y .v

A further object of theinvention is to associate with the indicator a bell which can be rung from the exterior and also to arrange the annunciator so that it has `a pleasing exterior appearance and suoli that it can be installed at comparatively small expense and when installed will be positive in action.

With the abo-ve more important objects in view the invention consists essentially in the 'arrangement 4and lconstruction lot parts here' in-after more particularly describedl and llater pointed out inthe appended claims,"y

Vreference being had to the yaccompanying :drawing in whichi f Fig. 1 is an exterior view of the indicator as it appears applied on the door.

Fig. 2 is an interior view thereof.

Fig. 7 is a sectional view at 7&7 Fig. 4 and showing the key hole slot. l Fig. 8 is -a reverse view of the rotary sign.

In the drawing like characters of .reference lindicate corresponding Aparts in the several figures. Y

On the front of the door 1 I permanently 50 mount a somewhat elliptical shaped block 2 and above this I locate a case 3 of fanciful l shape, the case presenting adial 41 having the hours indicated thereon-and being provided with a central spindle 5 suppliedwith a pointer 6.- Inside the door the spindle is fitted with a finger piece 7 `and a pointer'8, the pointer operating over a.v further time dial 9, the 'arrangement being such that both pointers will indicate. the same time when turned bythe occupant of the house. Obviously, by manipulating the linger piece 7 one can set the indicator or hand 6 to show Va fixed time, which time'will indicate when the party will return.

The block'2 .hastheifront face thereof Vgouged out tovprovide a front cavity 1() in which I mount a sign board or plate 1'1, the ends ofthe plate terminating in end spindles l2 and 13 rotatably mounted in the ends of the block. The plate is designed to normally close the enti'anceto the cavity and the cavity is provided to allow the plate to rotate. On one side of the plate I print the word Out and on the otherv side the word In, with a resultthatone, by observing the plate, can determine whether the occupant is in or out. Centrally the plate is provided Vwith a stop lug 14 adapted to* enter receiving notches 15 and 16 provided in t-lie block and limit the swing of the plate.

The plate-is controlled Vand manipulated from the interior of the door by the parts now described. Y

On the' spindle 13 of the plate I mount a pulley 17 which is suitably pocketed within the block and is protected by a guard plate 18. To the back of the 'v door I secure va bearing plate 19 which carries anopposing pair of lugs 2O and 21, the lugs supporting a pin 22 on which I mountrotatably a further pulley 23.*. An elongated thimble like cap 24 isv attached tothe back of the plate 19 and encloses the latter pulley and yhouses a coiled spring. 26, Aone end of which is seated at the base of the lugs and the other end of which is connected to a pushpin 26 which is provided at its .outer end with a knob 27 and is supplied with a contracted neck 28 adjoining the knob. f

The push pin passes slidably out through a key hole slot 29 provided in the cap and the neck of the pin 26 is designed such that the pin can be locked inV its inner position by entering the neck in the slot. TheV spring the lower endof which is'suitably-anchored to the plate. The latter spring is housed within a suitable casing 32. The spring' is considerably strongerthan the spring-32 and in its extended position, such being vwhen the pin 26 is outhiholdsthe spring l extended, the line being taut. n

The plate 11V is set .suchithat when the push pin is out the plate exposes, atthe outer side of the door, the wordfln. By

:properly arrangingthe parts the pushing `in of the pin 26 Vwill cause the pulley- 17 to 20.

rotate. one half revolution, withftheresult that the plate 11 is rotated a corresponding amount and the word 0ut is exposed.

lnfconnection with the operationbf the pulleys I might explain that whenthepush spring 25 is forciblyeollapsed andthe spring Sl'takes up theslack inthe line. Consequently, the pulley i7 islrota'ted. Upon the push pin 'being released,ho.wever,\the springQ pulls the line as it is strongerlthan the spring 31. This arrangement' isan -eX- erates Very satisfactorily.

1 also embody a-bell y33 with my annuneiator, thek bell being mounted on the inside.'

of the door on the plate `19 andbeingop- .eratedby alspring pressed push' knob 34, exposed' at theouter side of the door. IT-hebell indicated is'of thewellknownI type .em- I bodying a spring whichcanfbewoundnp ybyturning the bell gongandfhas/theham- `.mers normally locked but-adaptedto strike.y

37 and terminates in a the gong of the bell when released.

.l Vhave not considered it -necessary..to en-1 ter into a detailed description of the bell partsbut herein `show how the push knob controls the bell. A push bar 35 is-assooiated with the push knob v34h-and.Y passes slidably through the door andv is formed with a head 36 presentino aninclinedface nger trip 38. A sliding plunger 39 rides the face 37 and suitably fastened/to the bell framejwlhis spring engages withthe` arm .4l of the 2biellliammer 42, and in the forward positionV of the'push knob, looks thehammer v,against movement. Upon the push knob, however, being pushed inwardly the plunger Vforces the spring 4l() upwardly and releases it from.

the hammer arm. rlhe hammer arm carries the escapement 43 of the' bell mechanism and when the hammer arm is released the hainmer strikes the gong. v

lt will be apparent that this device will part oftheequipmentfsdthat' it can be used when the sign plate indicates that the party is in.
